Subject: checkpatch: make email address check case insensitive
Instead of checkpatch requiring the patch author to exactly match the
signed-off-by tag, commit 48ca2d8ac8a1 ("checkpatch: add new warnings to
author signoff checks.") safely relaxed this requirement.
Although the local-part of an email address (local-part@domain), may be
case sensitive, exploiting the case sensitivity of mailbox local-parts
impedes interoperability and is discouraged. Mailbox domains follow
normal DNS rules and are hence not case sensitive. (Refer to
https://datatracker.ietf.org/doc/html/rfc5321#section-2.4.)
Further relax the patch author and signed-off-by tag comparison by making
the email address check case insensitive.
